Super black holes bombard the Earth with powerful cosmic rays

New astronomers' research has shown that the Earth is often under the attack of high-energy particles in cosmic rays, due to the massive supermassive black hole in the center of the Milky Way.

In the study published March 16 in the journal Nature, astronomers operating the High Energy Stereoscopic System or the HESS Observatory in Namibia say that for the first time they can detect cosmic ray sources . This source can emit cosmic rays with energies 100 times greater than the Large Accelerator (CERN) on the French and Swiss borders.

" The most feasible machine that can promote this cosmic ray is the black hole in the center of our Milky Way ," Tech Times quoted Gavin Rowell at the University of Adelaide, Australia, a research team member.

The center of the Milky Way is the home of objects capable of producing high-energy cosmic rays, including a surrounding nebula nebula, remnants of supernova explosions and massive dense star clusters. However, the most feasible and dominant source is the supermassive black hole called Sagittarius A *.

Cosmic rays interact with gas and light, producing gamma rays in a straight line, without being deflected by the magnetic field and acting as a trace. For the past decade, telescopes at HESS provide direct evidence of a very strong gamma ray source in the center of the Milky Way.

HESS measures the amount of gamma rays in the universe. Since then, scientists have been able to deduce the proton spectra accelerated by super black holes. Sagittarius A * is 4 to 5 million times the mass of the Sun, certainly promoting cosmic rays that bombard the Earth.

Intense activity made this space area one of the brightest celestial bodies in the sky for astronomers to study, from radio waves to high-energy gamma rays. According to the research team, Sagittarius A * was more active in the past, then turned into a source of cosmic rays in today's observations.

A black hole is an area in space that has such a large gravitational field that its gravity does not allow any form of matter - including light to escape its boundary (event horizon). . Black holes exist in many different forms, from cosmic objects with masses of stars to super-massive "monsters" in the center of galaxies.
